# Fail2Ban filter for catching failed accesses to most likely unwanted, exposing and dangerous files.
# This will catch a lot of different scanning tools that are trying to find vulnerable applications.
#
# IMPORTANT
# This filter is quite heavy. If you enable it for the nginx access log, it will have to run a giant
# regular expression on each line. Please check out the best practice wiki page for more information
# on how to enable your nginx configuration to minimize the load on Fail2Ban:
